2 Claims. (Cl. 16-431) This invention relates to a door-hinge of thebutt type embodying a pair of leaf sections united by a pintle such asare commonly employed in hingedly mounting swinging doors in casings forhorizontal swinging movement with one of the leaf sections countersunkin an edge of the door and the other leaf section countersunk in thejamb of the door casing, the invention more particularly pertaining tohinges of the above character embodying a means whereby the leafsections thereof may be adjusted to compensate for sagging of the doorwith consequent misalignment with its casing.

Various constructions have heretofore been devised for embodiment in theleaf sections of a hingle whereby the sections may be adjusted on a doorjamb to effect alignment of the door relative to its casing so as toavoid the use of shims as commonly employed for such purpose, but suchconstructions have notbeen standardized nor come into extensive useprobably because of prohibitive cost of manufacture with consequentincrease in selling price or cost to the consumer as compared with thecosts incident to the common butt hinges now on the market.

The primary object of the invention is to provide an adjustabledoor-hinge for the purpose specified which is so formed as not tomaterially increase its cost of production relative to that ofconventional non-adjustable hinges.

Another object is to provide a means for rendering the leaf sections ofa hinge adjustable to vary the position of the hinge pintle laterallyforward or back as occasion may require to vary the tilt of the doorcarried thereon relative to its casing, which means is of such characterthat it may be designed for application to a conventional hinge as anattachment shereto either under production or on-the-job, or which maybe embodied as an integral part of the hinge in the course ofmanufacture thereof.

With the foregoing objects in view together with such other objects andadvantages as may subsequently appear, the invention resides in theparts and in the combination, construction and arrangement of partshereinafter described and claimed and as illustrated by way of examplein the accompanying drawing in which:

Fig. l is an isometric view of a door-hinge showing the rear faces ofthe leaves thereof with the invention applied:

Fig. 2 is a view in cross section taken on the line 2-2 of Fig. 1:

Fig. 3 is an enlarged detail in section of one of the hinge leafsections taken on the line 3-3 of Fig. 1, show ing it as mounted on ajamo and depicting the manner of effecting adjustment thereof:

Fig. 4 is an isometric view of a modified form of the invention showingit as an embodiment of the hinge leaf section; and

Fig. 5 is an end view of the hinge shown in Fig. 4.

Referring to the drawings more specifically AA indicate the pair of flatrectangular leaf sections of a hinge which sections are of equalthickness throughout and are pivotally connected together by a pintle Bin the usual Each leaf, section A is formed with screw receivingapertures here shown as three in number and embodying a single apertureC located intermediate the ends of the leaf section contiguous the outermargin thereof and also including a pair of apertures D-D spaced apartin alignment longitudinally of the leaf sections and located in inwardlyand outwardly spaced relation to the aperture C. Manifestly the hingeleaf section may be equipped with any suitable number of screw receivingapertures but for adaptation to the present invention must essentiallyembody an arrangement of the apertures which will afford one or moreapertures spaced relative to each other laterally of the leaf section.

The invention resides in providing the leaf section A with a singlelongitudinally extending narrow and shallow rib E protruding from therear face of the section between the laterally oifset apertures CD,which rib is preferably arcuate in cross section to formra rocker whenseated on the surface to which the leaf section is applied.

The rib E is characterized by having side margins which- In the form ofthe invention shown in Figs. 1 m3 the rib is shown as comprising astripeof suitable material preferably metal which strip is arcuate incross section and has a flat under face which is seated on the under--side of the leaf section and is securely engaged therewith in anysuitable manner as by means of an adhesive. The strip 6, constituting arocker, extends parallel with the longitudinal margins of the leafsection preferably throughout the length 'ofthe latter as shown inFig. 1. This construction is advantageous in that it may be carried outeither in the factory in producing the hinge as an article ofmanufacture or it may be applied as an attachment to a conventionalhinge, since a person of ordinary skill being supplied with the loosestrip 6 may readily mount it on the leaf section.

In the form of the invention shown in Figs. 4 and 5 the rib Econstitutes an arcuate protrusion 7 which is formed integral with theleaf section as by a stamping operation which construction is effectedin the manufacture of the hinge.

In the application and operation of the invention the hinge is mountedin the usual manner, one of the leaf Sections A being mounted on theedge of a door and the other leaf section being mounted on the door jambwith the leaf sections recessed and secured in place by the usual woodscrews 8 and 9 screwed into the door jamb through the apertures C and Drespectively.

In thus mounting a leaf section A the rocker m'b E thereon will seatalong its outer portion or ridge and between its side portions on thebottom 10 of the recess 11 in which the leaf section is mounted, asshown in Fig. 3, whereby the underside of the leaf section on oppositesides of the rib E will be slightly spaced by the rib from the bottom ofthe recess and will normally be disposed in parallel relation theretowith the ends of the leaf sections abutting the ends of the recess.

In eifccting alignment of the door with its casing, either wheninitially mounting the door or subsequent thereto, in event of saggingof the door such alignment is accomplished by tilting the leaf section Aon the rocker rib E to laterally shift the axis of the pintle B eitherrearwardly, as indicated by the dotted lines a in Fig. 3, or forwardlyas indiacted by the dotted lines b. This adjustment is effected byloosening the screw 8 and tightening the screws 9 to tilt the leafrearwardly, as indicated by the dotted lines a or conversely byloosening the screws d and tightening the screw 8 to tilt the hinge leafsection A forwardly into the position indicated by screw 8 or 9 is thentightened to seat on the hinge leaf to then co-operate with itscompanion screws to securely hold the leaf section stationary in itsadjusted position. In some instances adjustment of either one or theother ofthe leaf sections may only be required to effect align ment ofthe door -with its casing, but there may be occasions when it will benecessaryto adjust both leaf sections. p j

In order to obviate or at least minimize objectionable projection of theouter face of thehinge leaf relative to the surface face of the door orcasing leading from the margin of'the recess 11 when the hinge leaf ismounted in :the recess in a tilted position on the rib E, the com hinedthickness of the fiat leaf A and-the arcuate the tiltof a hinge leafsection witout the aid of shii'ns'and without materially increasing-thecost of the hinge.
